Yes, it’s a different Android based OS. It’s privacy focused, hence having this feature, and only supports Google Pixel devices.
Android is just a version of Linux, so anyone can make a fork of it. Most Android device manufacturers do this, including your device having Samsung’s rendition of Android and my OnePlus having OxygenOS (soon to be ColorOS), but anyone can do the same if they’d like. LineageOS is another super cool Android project.
This is a GrapheneOS feature.
Oh, so its a different operating system or something?

GrapheneOS is a custom fork(? Correct me if I’m wrong) of Android that retains most of the features but has a private and de-googled experience.
